BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 417,139, dated December10, 1889.

Application filed July 8, 1889- Serial No, 316,742. No model.)

To all whom, it may concern:

Be it known that I, RUDOLPH BLoEsEn, of Scranton, in the county ofLaekawanna and State of Pennsylvania, have invented certain new anduseful Improvements in Bottle-Stoppers; and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanyin g drawings, forming a part ofthis specification, and to the letters of reference marked thereon.

The present invention relates to certain improvements in that class ofclosures for bottles commonly known as swing-stopper fasteners-that isto say, those in which the stopper is mounted on a bail attached to theneck of the bottle, and adapted, when opened, to swing down out of theway to permit of the free escape of the contents. \Vhile stoppers ofsubstantially this general description have heretofore been constructed,it has been found impractical to employ stoppers which ex tended anydistance down within the mouth of the bottle without also making use ofcomplicated and objectionable combinations of links and bails whichenable the stopper to be raised vertically the necessary distance toclear the mouth of the bottle when being opened or closed; and it is theobject of my present invention to overcome this defect and to provide astopper employing, if desired, but a single bail for its attachment tothe neck of the bottle, and which may extend well down into the mouth ofthe bottle and not only clamp over the mouth, but expand within thesame, thus forming a most efiicicnt and practical stopper of the classmentioned.

To the end above indicated the invention consists in certain noveldetails of construction and combinations and arrangements of parts, aswill be hereinafter described, and pointed out particularly in theclaims at the end of this specification.

In the accompanying drz'iwings, Figure lis a side elevation of the topof a bottle having a stopper applied thereto constructed in accordancewith my invention. Fig. 2 is a vertical sectional view of the same,taken through the bail. Fig. 3 is a view of the stopper thrown open.Fig. at is aperspective view of the locking-lever.

Similar letters of reference in the several figures indicate the sameparts.

a In the preferred form of stopper shown in the drawings the portionextending down into the mouth of the bottle is made to expandlaterallyto fill and tightly close the same by being compressed between the topand bottom plates A and B, respectively, the latter being connected tothe end of the central pin or stud C, which extends up through top plateA, and is provided with an aperture above said plate through which thebail D passes. The top plate A is provided at the center with adownwardly-extending annular projection A, around which fits the washeror flanged upper portion E of the elastic center portion E, the body ofthe latter being held directly between the said projection and thebottom plate.

A cam-lever F, preferably having arms ex-- tending on each side of thecentral pin or stud, is pivoted on the bail and adapted to co-operatewith the top plate and central pin or stud to bring the two platestoward each other, and compress and expand the elastic center portion,as well as force the top plate and flange E, which is of substantiallythe same diameter, down over the mouth of the bottle, forming a doubleseal, as will be readily understood. V

As before intimated, the locking-lever may be of any approved style, butis preferably so formed as to be capable of application to the bailafter the same is bent up into shape, for which purpose the bearings inthe lever for the bail are formed open, and are adapted to be closed byhaving the armsf bent around, as illustrated in Fig. l.

A stopper constructed as thus far described would in a large measure beopen to the ob j ection heretofore pointed out-11. 0., the difficultyexperienced in removing the stopper from the mouth of the bottleandparticularly is this the case where the stopper extends down into themouth of the bottle some distance, as shown. In order to overcome thisdifficulty and enable the stopper to be easily withdrawn, the bail H,instead of being piv- 'oted, as heretofore, on a line taken through thevertical center of the bottle-neck, is pivoted to one side thereof,whereby the are described by the top-of the bail, instead of passingnearer to the edge of the bottle-month as it moves off to the side,passes farther away from the same as illustrated clearly in Fig. 1, theline K representing the are described by a bail constructed inaccordance with my present invention and the line M the are described bybail as ordinarily constructed. From this it will be seen that thestopper is given plenty of room to clear the month of the bottle, eventhough it be quite a long one, in which instance it will be necessary totilt the stopper as it is opened, and by extending the locking-lever onthe side of the bottle opposite to that on which the bail is pivoted, asshown, it will be seen that a continuous movement of the lever first torelease the compression of the elastic center portion and then to throwthe stopper to the side, serves to open the bottle almostinstantaneously, preventing all danger of the contents, when aerated,from being showered around by comingin contact With the stopper whenpartially opened.

In the preferred form of bail illustrated it is extended straight downin lines substantially parallel with the vertical center of the bottle,and at the level of the neck is bent at substantially right angles andextended out to the side, as shown, the ends being pivoted in eyesformed by coils of the neck-wire or in any other preferred or well-knownmanner.

I am aware that expanding stoppers have been connected to the mouth ofthe bottle by a loop connected to the stopper at one side andsurrounding a bail or neck wire at one side of the vertical center; butthe connection so formed is a loose one, the loop being in no sense abail nor adapted to assist in holding the stopper in the mouth, nor doesit guide the stopper intoposit-ion, as does the bail herein described.

Having thus described my invention, what I claim as new is 1. Inabottle-stoppcr, the combination, with the swinging bail pivoted at oneside of the vertical center of the bottle and the stopper pivoteddirectly on and held against outward movement by the bail when locked,of the locking-lever, also pivoted on the bail, and engaging the stopperto close the mouth of the bottle, substantially asdescribed.

2. In a bottle-stopper, the COTl'lblllFttlOIl, with the bail pivoted atone side of the vertical center of the bottle and the stopper carriedand held against outward movement by the bail when locked, having thecentral pin or stud through which the bail passes, with the top andbottom plates and the elastic center portion, of the locking-leverpivoted on the bail and engaging the top plate to bring said platestoward each other and expand the elastic center portion within the mouthof the bottle, substantially as described.

3. In a bottle-stopper, the combination, with the bail hinged at oneside of the vertical center of the bottle and the stopper having thecentral pin or stud through which the bail passes, the bottom platesecured thereto, the top plate having the central downwardlyeXtendingannular projection, and the central elastic portion below saidprojection, having the top flange surrounding said projection, of thelocking-lever pivoted 011 the bail and engaging the top plate to movesaid plates toward each other and clamp the said flange against themouth of the bottle and expand the central portion within the same,substantially as described.
